Annexation of Provinces

I’ve been playing this game for awhile, as well as three of its family members, Supremacy 1914, Conflict of Nations, and New World Empires. I’ve realized that this game is missing something that the others have, Annexation. (Besides Supremacy, because there are no cores.) Having the option to annex provinces and cities would make the game a lot more interesting, realistic, and easier to create large empires, which can lead to giant wars between multiple massive empires. This will also give a better chance to small nations in ‘All countries, all in’ as they can annex the lands they take, and get the resources and manpower that their nation lacks. To annex a province, you must frist occupy it. (Obviously) It will then take Goods, Food, and Money to annex it. The amount of Goods, Food and Money should depend on the morale and population of the province. The cost shouldn’t be huge, and the cost shouldn’t be equal to every province. It would not be fair if, let’s say, you invaded the Soviet Union. To annex Moscow, it takes 5,000 Goods, 5,000 Food, and 30,000 Money. But, it would also cost the same amount to annex a random empty province in Siberia, which would lead to people ignoring non-cities. Going by population should make it so that cities are costly to annex, and provinces are cheap to annex, but obviously, you’d be annexing a lot of them. The benefit of annexing a province would be an increase of resource production. (Money, Manpower, and any vidal resource that may be in the province.) The production would go to anywhere from 35%-60% production. 50% production would make sense, but I don’t control you guys, and even having the option to annex provinces would be greatly appreciated. If you annex a province, and the province is taken, it would lose its annexation, and taking back a province that was previously annexed should have a stable morale, similar to when you retake a core-province, but it would be in the 30s, so morale is low, but not rebellious. This would allow people to more easily retake province that they’ve held on to and have annexed. The morale of the province should need to be 35% before annexing, and or take time to annex the province. Theses are all ideas, and any of them can be changed or modified.
